the modified reversed contralateral axial rotation position

Conditions: Disc Prolapse With Radiculopathy

Summary: this study aimed to investigate the effect of specific three-dimensional (3d) positions of the trunk on patients with lumbar discogenic pain with radiculopathy aiming to find a position that directly decompresses the impinged root as well as the effect of this position on the csa of the l3-l4, l4-l5 and l5-s1 intervertebral foramen (ivf) using 3d-ct scan imaging of the real spine

background: management of lumbar discogenic pain is complex and there is ongoing debate over both surgical and conventional conservative treatments. purpose: this study aimed to investigate the real-time effect of specific three-dimensional (3d) positions of the trunk on patients with lumbar discogenic pain with radiculopathy aiming to find a position that directly decompresses the impinged root as well as the effect of this position on the csa of the l3-l4, l4-l5 and l5-s1 intervertebral foramen (ivf) using 3d-ct scan imaging of the real spine. methods: this study was conducted on ninety male patients (30 in each group), ages ranged from 20 - 40 years old, and were diagnosed with unilateral lumbar disc prolapse (group1: l3-l4), (group 2: l4- l5) and (group 3: l5-s1) for at least three months in a radiology center specialized in the spine (egyscan center). each group was imaged three times (from the supine position, then from the oblique position after 10 minutes, and finally from the oblique position again after 48 hours). the oblique image was taken during a specific trunk position the modified reversed contralateral rotation (side-lying on a hard pillow with side bending to the non-affected side and rotation to non affected side).the csa of livf and slr test were assessed at the three times of testing results: the mixed design manova revealed that the mean values of the livf csa and the slr significantly increased in the reversed contralateral rotation position after 48 hours compared to the same position after 10 minutes and the supine position in the three tested groups (p=0.001). moreover, the livf csa and the slr significantly increased in the reversed contralateral rotation position after 10 minutes compared to the supine position in the three tested groups (p=0.001). conclusion: modified reversed contralateral rotation of the trunk has a real-time decompressing effect on patients with lumbar disc prolapse as well as a significantly increasing effect on the csa of l3-l4, l4-l5 and l5-s1 ivf in the three tested groups. changing the spine position from supine to the modified reversed contralateral rotation position had a great clinical value on patients with lumbar discogenic pain with radiculopathy.
